"Young Master, Xiao Xi has brought you a change of clothes!"
Li Zexuan returned to Drunken Wind Pavilion. About 15 minutes later, Faubert did not come to deliver the materials, but Xiao Xi came to deliver the clothes instead.
"Mm, thank you for your hard work. Xiao Xi, you can go back after you put these clothes in the room!"
Li Zexuan leaned on the table as he recalled the knowledge of physics and chemistry from his previous life.
"Young Master, Madam is worried that you will suffer here alone, so she asked Xiao Xi to stay here and take care of you! Xiao Xi will go back and bring your three meals a day! "
Xiao Xi hugged the bundle that she brought over and turned around to say.
"Mm ~? Did my mother really say that? "
Li Zexuan raised his head and asked.
"Of course … Yes, Xiao Xi went to prepare a room for you!"
Xiao Xi replied with a slightly red face. She then hurriedly turned around and carried the bag into the room.
In fact, after San Bao sent the news that Li Zexuan would be staying in the workshop for a few days, Madam Li did not think of sending a maid to take care of her son's daily life. It was Xiao Xi who weakly mentioned it, so Madam Li sent her over.
Thinking of Madam Li's meaningful gaze and smile when she arrived, Xiao Xi was so embarrassed that her ears turned red.
.....
"Boss, these are the materials that Butler Fu asked me to bring over!"
Not long after Xiao Xi went into the room, Song Xiaosi came over with a bag. After the previous lesson, Song Xiaosi's smile now had a tinge of caution. He was no longer as impulsive as before.
"Mm."
Li Zexuan took the bag and checked it carefully. He then nodded with satisfaction and said, "Very good! Not a single one is missing. Xiao Si, you can go back now. It's almost time for work! "
"Young Master, I'm not in a hurry. I can stay in the workshop at night. Why don't I serve you here? If you have any orders, I can run errands for you, right?"
Song Xiaosi smiled politely.
"No need. I don't have anything to do here. I can do it myself. Xiaosi, you should go back!"
Li Zexuan smiled and replied.
At this moment, Xiao Xi finished tidying up the room. She came out and said, "Young Master, your room is ready!"
"Mm, thank you for your hard work!"
Li Zexuan nodded.
"Ah! Young Master, then, then I will take my leave! "
When Song Xiaosi saw Xiao Xi, he immediately reacted. At the same time, he hated himself for being so talkative. His Young Master was a beautiful woman, why would he need his help?
"Sigh!"
When Li Zexuan saw Song Xiaosi running away, he knew that Song Xiaosi was overthinking. Li Zexuan wanted to call him back, but he thought better of it. There was nothing to explain.
"Xiao Xi, there's still a room on the east side. Go and clean it up yourself. I'm going to start working now!"
Li Zexuan picked up the large bag of experimental materials and walked into the room as he smiled at Xiao Xi.
"Oh!"
When Xiao Xi saw that Li Zexuan did not need her help, she replied with an "Oh" and went to the other room to tidy it up. After all, she was going to stay here at night. She could not possibly sleep in the same room as Li Zexuan, right? Although she had thought about it before, but …
.....
"Heh, after transmigrating for so long, I'm finally back to my old profession!"
Li Zexuan placed the bag of materials on the "experimental platform" that he temporarily put together with four long tables. Looking at this simple "laboratory", he felt a little emotional.
As an engineering student, and one that specialized in engineering, he had soldered countless circuit boards in the laboratory. He did not expect that after transmigrating to the Tang Dynasty, he would still have to do his old profession. The difference was that his current laboratory conditions were even worse. Of course, the experiments he did were more basic and simple. It could not be compared to modern integrated circuits.
"Let's get to work. Today, I will make the battery come to this world more than a thousand years earlier. Haha! Dear Mr. Volt, I'm sorry for stealing your invention! "
Li Zexuan rubbed his fists and rubbed his palms as he muttered to himself eagerly.
That's right, what Li Zexuan wanted to make was the simplest Volt battery. What? You think that Volt batteries are too weak? Why not make a generator?
F * ck, Big Chest Brother, it's easy for you to say that. You haven't even learned how to walk and you want to run away. Do you think that generators are that easy to make? You transmigrated to the Tang Dynasty, why don't you try making one for me? Can you make one without one or two months? Li Zexuan wanted to immediately create electricity and then realize the next step of his plan. How could he use one or two months to make a generator?
Li Zexuan watched the TV series "The Myth" in his previous life. In the series, Yi Xiao Chuan, who was played by Hu Ge, transmigrated to the Qin Dynasty. Because his phone ran out of battery, he made himself a hand-cranked generator … Of course, this was the scriptwriter's nonsense. In fact, that thing could not generate electricity at all.
Okay, magnets existed in ancient times. The wires used were the gold threads from the clothes of the future Liu Bang's wife, Lu Hou. However, those gold threads did not have an insulating outer layer. When they were wrapped into a coil, it was no different from a lump of gold. The scriptwriter did not know that real generator coils were covered with enameled wire. Not to mention, to charge the phone, didn't he need an interface cable?
Li Zexuan, who was a science and engineering student, was troubled by this for a long time. At that time, he also thought that if he really transmigrated to ancient times, when he needed to charge his phone, he should "adapt to the time" (ancient materials were limited). What kind of device should he invent? Should it be a simple hand-cranked generator or something else?
What? You said that there was no signal in ancient times, so why did you need to charge your phone? You could use your phone as a video camera. Could it be that your phone could only be used to make calls? If there were some pornographic content in your phone, you could contribute it to the emperor. You might even have a lifetime of glory and wealth …
After thinking hard and letting the dog stand him up on the Internet to find a needle in a haystack, he really found it …
In the year 1800, the famous scientist Volta invented the world's first battery, which was also the ancestor of modern batteries. He did not know why those idiotic translators in China would sometimes call it Volta and then Volta. Li Zexuan's mind was often confused when he was in middle school.
Through experiments, he found that when a piece of paper soaked in salt water was sandwiched between two different metals, electricity would be generated. He soaked the blotting paper in salt water, stacked it with a layer of silver, a layer of blotting paper, and a layer of zinc. Then, he used a wire to connect the top layer of metal to the bottom layer of metal. He found that he could measure the voltage and current. This device was now called a "voltaic battery".
The principle of a voltaic battery was: when different metals came into contact with an electrolyte solution in pairs, the ions in the solution would form a directional movement and thus generate an electric current.
Until now, the dry battery that we used was a modified voltaic battery. In the dry battery, a paste of ammonium chloride was used instead of salt water, a graphite rod was used instead of a copper plate as the positive electrode of the battery, and a zinc sheet was used as the negative electrode of the battery.
Compared to making a generator, wasn't it easier to make a battery?
